Exciting. After opening the outer oven cylinder someone was in that section before as the shock compound has been removed. And the failure appears to be the inner oven heater is open. A better description of the unit. The FE-15a oscillator assembly is about 6" nd 3 sections.
Outer tuning caps and at 110 F it also contains the outer oven control opamp for temperature. Middle contains the inner oven control opamp and either oscillator buffer or the oscillator. (Guessing buffer.) The heater transistor appears bad/shorted. Inner or deepest unit. Covered with outer heater winding. Suspect a inner heater winding Open Perhaps the oscillator. Going to find out. Must unsolder the outer winding and a few screws.
